5分鐘前 湖北莫諾轉(zhuǎn)子價(jià)格合理 螺耐斯[螺耐斯10e361c]內(nèi)容:B、轉(zhuǎn)子B, rotors轉(zhuǎn)子的結(jié)構(gòu)也非常簡(jiǎn)單,主體是鋼制桿件,一般外涂耐磨耐蝕的鉻合金材料。其作用是傳遞動(dòng)力和寫定子形成密封腔。The structure of the rotor is also very simple, the main body is steel rod, generally coated with abrasion resistant and corrosion resistant chromium alloy material. Its function is to transfer power and write the stator to form a seal cavity.C、回轉(zhuǎn)筒C, rotary barrel回轉(zhuǎn)筒也就是一根內(nèi)徑較大的油管或空心定子筒,接在定子的上部以給轉(zhuǎn)子和抽油桿桿柱以較大的回旋空間,防止轉(zhuǎn)子和抽油桿因偏心運(yùn)動(dòng)磨擦磨損油管。A rotary cylinder is also an oil tube or hollow stator barrel with larger inner diameter. It is connected to the upper part of the stator to provide larger swirl space for the rotor and sucker rod string, so as to prevent the rotor and sucker rod from attrition wear due to eccentric wear.
單螺桿泵工作時(shí),兩端分別作用著液體的吸排壓力,因此對(duì)螺桿要產(chǎn)生軸向推力。螺桿泵廠家建議對(duì)于壓差小于10千克力/cm2的小型泵,可以采用止推軸承。此外,還通過(guò)主動(dòng)螺桿的中央油孔將高壓油引入各螺桿軸套的底部,從而在螺桿下端產(chǎn)生一個(gè)與軸向推力方向相反的平衡推力。
單螺桿泵和其它容積泵一樣,當(dāng)泵的排出口完全封閉時(shí),泵內(nèi)的壓力就會(huì)上升到使泵損壞或使電動(dòng)機(jī)過(guò)載的危險(xiǎn)程度。所以,螺桿泵廠家建議使用時(shí)在泵的吸排口處,就必須設(shè)置安全閥。
